It is a small deciduous tree, to 20 m in height with pale grayish brown to blackish brown, exfoliating bark. Young twigs are pale yellowish brown. The dark green leaves are obovate, 10–18 cm long and 4.5–10 cm broad, with a 1–3 cm petiole. Fragrant flowers appear before leaves, erect, cup-shaped, 15 cm wide, with 12-14 tepals that are white to rosy-red. The fruit is a cylindric aggregate of follicles 6–18 cm long.

Fossils of Magnolia sprengeri have been described from the fossil flora of Kızılcahamam district in Turkey, which is of early Pliocene age.[1]
